It's an opinion, he's entitled to it, as are you to yours. Making comments like the one you just left LEFREAK has one end result, you look like a prat (again, only my opinion).
As for asking him if he would "travel to that concrete spot if you had the means", you're proving his point entirely. He said the photography wasn't particularly good (something I agree with) but called them "Powerful photos" due to their environment and the background history & stigma attached to there.
